In my VB.NET application I compare words that are recorded using IPA, many of which have many diacritic marks. In one of the comparisons, I compare the words character by character. But when I iterate over the characters, the diacritic marks come out as separate characters (as I would expect since this is unicode)However, a u character is different than a u plus an accent for the purposes of this program and needs to be distinguished.
View 1 RepliesHow to check the Single byte character (e.g. English) and Double bytes character(e.g. Chinese) ?
Since I want to printing out their code which are representing in Hex.
However, Single byte character is using 2 digits of Hex. And Double bytes character is using 4 digits of Hex.
So, how can I check them and output with more readable pattern ?

I have a string like "Hello'World" and a Data Table with some records in it. One of those records is "Hello'World".he problem is, when I do a .Select in the Data Table, it only tries to search for the "Hello" part and throws an error on "World" because it interprets the ' (single. cuote) like the closing cuote on sql.DataTable.select("text = 'Hello'World'")I have gone through msdn doc, and it says I can escape some characters with [] brackets or f.slashes , but I just can't figure out: .select("text = 'Hello[']world'")
View 1 RepliesI am trying to do a SQL query that checks for the presence or absence of a character's occurance in a field / column as a condition to retrieve the row. In this case I only need to test for existance of the specified character and in a similar query to test for the non existence. Not where it is or how many, just is it there or is it notI am using VB express.net 2008 and it uses, I think, MS SQL Server 2008.Using VB's instr() I can tell straight away if a string does or doesn't contain a character, but I would like to know this before I retrieve the row.
using the
WHERE .... and [mytable.myfield] LIKE 'Q'
or
WHERE .... and [mytable.myfield] NOT LIKE 'Q'
produces a result, but not a correct result. It does something but I can not say that it is working even part way.CHARINDEX gets an undefined function error MATCHES also gets an undefined function error?CONTAINS looks like it should work but I am still getting sytax errors with it, so I don't know how to use that predicate yet.
I have been assigned a task to create a basic hangman program and I need help to figure out how to show the letters that the user has guessed correctly without displaying any of the other Characters.The word that the user will be guessing is in a label the user will be guessing letters by clicking buttons This is a piece of the code for one of the buttons the user can click to guess the letter "C":
btnc.Visible = False
Guessletter = "C"
If lblword.Text.Contains("C") Then
*this is the part where I become stuck*
End If
How to read a single character each time, from a text file using vb.net? I mean that if the txt file contains code as " my name is...".It should be read initially as :'m'..after some time it should show 'y'. then 'n'.'a'..'m'.'e'.like that..

For example for the data: sales(10,7,12,5,15)
The output would be

how to change the integer value from within the array into a certain number of a single character.
I have two arraylists that contains links in one and the root url in the other. Sometimes the lists dont equal in number and I would like to iterate through the links list and if it contains a matching root url add it to a third list but also avoid any duplicates. I tried this but am not getting consistent results.

I have a class that gets 2 label controls passed to it byRef. So, while my class is being executed I want the labels on the form to be updated. This works Most of the time, but sometimes it seems the form stops updating till the class has finished its process...below is some of the code that I am using to do this...
Public Class clsImportWWDB
Implements IDisposable
Private strSearchTag As String = "" 'Last Tagname of value scanned
Private intMeldsFound As Int32 = 0 'Number of Alarm Messages Found
Private _MyForm As Windows.Forms.Form
Private _FileName As String

My project has the need to build consistent urls similar to the ones here on stackoverflow. I know how I "can" do it by running the string through multiple filters, but I'm wondering if I can do it all with a single method.Basically I want to remove all special characters, and replace them with dashes BUT if there are multiple dashes in a row, I need them to be a single dash. How can I implement this as clean as possible?

I'm having an issue with a program. It seems to run (continuously) any amount of time from a few days to about a week.Eventually, and seemingly randomly I get the following Errror. None of the users see a consistent item that is causing the hang, and sometimes it's even just running with no interaction with the user.I just get long signature alpha numerics as a debugging tool.Is there any way to
a) force my program to kick out of the hang if it detects one, (and I guess, how could I write a separate thread to detect a hang?)
b) find out where my program is hanging?
c) if none of these options are viable, some coding practices I might be doing wrong that I could change to help avoid this?

Is there a better way of doing this so I get the result I want for my usage code?

How do I write an expression to calculate all characters of each row by my own defined value to each character = all the A and B and C and etc. will be as 2 and all I and J and whatever ... will be 1 so I need an end result of the total.
View 3 RepliesI am working on a sub that essentially needs to open a text file, and replace all instances of a certain character with a unicode character. I'm trying to do this by reading the original text file byte by byte, converting it to a character, and then either adding that character to a memory stream or writing the unicode character to the memory stream. Then I'm saving the memory stream to the original file.

For each character of this string I want a new character out of the string and then remove the character from the list of characters that still maybe used for other characters. It may not get the same character, you could basically just call this encryption, but it's not what I am making. I don't want to waste my time doing this one hour while VB can do this for me in <1 second.
I am writing a hangman type game and I am displaying the word to the user in a label as all *'s, but I cannot figure out how to have just one of the *'s changed in the label to the correct letter when the user inputs the correct letter into the text box and clicks the check letter button.Everything else in the program works perfectly, except for this part.[code]When I use the .Replace it changes all of the *'s to the correct selected letter.
